You need to install some libraries and stuff.  Instructions are at
<https://wiki.debian.org/Multiarch/HOWTO> but the short version is:

    dpkg --add-architecture i386
    apt-get update
    apt-get install libc6:i386

Oh... did you already do *part* of the Multiarch setup, but not all of
it?  That would have been useful information to include.

Once the /lib/ld-linux.so.2 interpreter is there, you should get more
informative results from ldd.
